Describe the bug
For a gradeable with peer grading, for a component that is peer graded, the peer graders should only be able to chose from the teaching staff prepared point & message common marks. They should not have access to the custom mark feature.
Why should we restrict custom marks? Well we are currently not displaying the use of custom marks by peers to the instructor or back to the students so the grades are confusing and look wrong. It would be overly complicated to add this in when there are other more pressing matters to address with peer grading.
NOTE: The instructor can configure the rubric to disallow custom marks for all components. This feature is functioning correctly for non-peer graded marks and should not not be modified.
Also, I think we should improve the on-page documentation about the use of custom marks. Anecdotally, I think they are over-used and the consequences surprise instructors. If custom marks are used, it is harder to adjust the points for common/shared marks after grading is completed to balance/curve scores for the class. Also, the custom mark points are stored in a separate table in the database so writing SQL queries to access the data is more complex.
